Obtaining Help
As soon as you are in a command mode, there are several ways to access help.
• To obtain a list of keywords at any command mode, do the following:
— Enter a ? at the prompt or after a keyword. There must always be a space before the ?.
• To obtain a list of keywords with a brief functional description, do the following:
— Enter
help at the prompt.
• To obtain a list of available options, do the following:
— Type a keyword followed by a space and a ?
• Type a partial keyword followed by a ?
— A display of keywords beginning with the partial keyword is listed.
Figure 3-3 shows the results of entering
ip ? at the prompt.
Figure 3-3. Partial Keyword Example
When entering commands, you can take advantage of the following time saving features:
• The commands are not case sensitive.
• You can enter partial (truncated) command keywords. For example, you can enter
int tengig
interface
for the interface tengigabitethernet interface command.
• Use the TAB key to complete keywords in commands.
• Use the up arrow key to display the last enabled command.
• Use either the Backspace key or the Delete key to erase the previous character.
Use the left and right arrow keys to navigate left or right in the FTOS command line. Table 3-2
defines the key combinations valid at the FTOS command line.
